That's one interesting photo.

Why I like LEDs on top of other lighting tech?
LEDs = Upgrade 95% of the applications. (That is if you avoid eBay's LEDs).


LED brainwash? No, people uses them cuz they work well for them.

I wish I could find SBMV lamps locally. The use of a small halogen lamp for the ballast is a good idea.

It is not small but a linear halogen of comparable power to the arc tube

They solve few problems this way :

In a standard SBMV lamp the filament and the arc tube "want" different fill in the outer. Heavy gas at high pressure to keep the filament from vaporizing, non-conductive gas at low pressure for the arc tube to warm up properly. So whatever you put in is not the best option. This way they can use the same fill as standard mercury lamp

The assembly of filament, arc tube and starting resistor on metal frame is tricky. It have been done partially by hand up to the early 2000's. Using a "ready" halogen lamp eliminates part of the challenge so this lamp is easier to manufacture

_maybe_ the limit on standard SBMV lamps for vertical burning position only (perhaps at least as long as the halogen is not below the arc tube)
